Investigation for large magnetic field enhancement of pressure induced-ferroelectric polarization in multiferroic DyMnO3

Abstract: We propose to perform neutron diffraction experiments under high-pressure and magnetic field condition for multiferroic DyMnO3, using WISH beamline in combination with hybrid-anvil-type high-pressure device. From our recent high-pressure neutron work on the similar compound TbMnO3, we concluded that the giant ferroelectric polarization is caused by E-type magnetic ordering for Mn-spins. (N. Terada et. al, PRB 93 081104(R) (2016)) However, magnetic field-induced polarization enhancement in high pressure phase with significantly large change (0.7 μC/cm2) is still unclear. In this study, we are going to investigate how the magnetic orderings of both Mn and Dy spins are changed by magnetic field under hydrostatic pressure up to 6 GPa, using the hybrid-anvil-type high pressure cell.
